Renault Nervasport ZC 2 / ZC 4

Anglicky (český popis chybí)

First shown at the 27th Paris Motor Show in October 1933 (although recognized by the French authorities as a distinct model one month earlier), the ZC 2 version received streamlined bodywork reminiscent of a period Chrysler product. The related Nervastella was called the "ZD 2". The body now featured a reclining grille and windshield, more rounded bodies with deeply skirted fenders and an integrated boot. The vent flaps are now larger towards the rear of the car and the front bumper now has a pronounced curving dip in the centre, all of which adds to the streamlined motif. The side-valve engine, while still retaining the 105 mm (4.1 in) stroke and basic structure used for Renault engines since 1905, received an increased bore (now 80 mm or 3.1 in) for a displacement of 4,827 cc (295 cu in). The tax horsepower increased to 28CV.Power remained as before, with this becoming somewhat of a handicap in a market where outputs per litre had begun to climb. Low-end torque increased, however. The wheelbase increased to 3,184 mm (125 in). Eight naked chassis were delivered to various coachbuilders.

For the next Paris Show, in October 1934, the design was yet again rounded off a bit (ZC 4). The wheelbase increased by about 7 cm (2.8 in) and the bonnet now sports four long chrome-capped vents, accenting its length. The front bumper is now of a two-piece design with a gap for the registration plate in the middle. The engine (as with all of Renault's sixes and eights this year) received an automatic choke and an optional engine starter which engaged when the throttle was depressed.
